484 APPENDIX. 



I now give you a short sketch of what I deem to be the principal 

 object of our cruise towards the Antarctic Circle : first, to reach as 

 high a southern latitude as can be attained, without hazarding the 

 safety of your vessel and crew ; and last, to make all the observations 

 that my former instructions have pointed out, including the dip and 

 intensity. 



In the event of parting company, you will rendezvous, first, at 

 Macquarie Island, if it should occur before reaching its latitude, 

 where you will remain forty-eight hours, off and on ; thence proceed 

 to the Emerald Isle, waiting on and off thirty-six hours, and from 

 thence to the south as far as the ice will permit, and continue cruis- 

 ing along its borders, between the longitude of 160° E. and 105° E., 

 until the 1st of March, at which period it is deemed the season will 

 become too far advanced to proceed south with any chance of success. 



On your return, you will proceed to the Bay of Islands, New 

 Zealand, where you will await my arrival, or find orders with the 

 American consul, resident there. 



If the Lord Auckland Group should lay in your path on your return, 

 you will find a secure harbour in that of Sarah's Bosom, in latitude 

 50° 38' S., longitude 166° 16' E. 



On your return, you will vary your route as much as possible, or 

 as the weather and state of your vessel will permit. 



In case you should not be able to reach the Bay of Islands, prior to 

 the 25th of March, you will thence make for the island of Tonga- 

 taboo, Friendly Group, where you will find me or orders directing 

 your further movements. (If no intelligence before the 15th of April, 

 you will then proceed to the Feejee Group of islands, Harbour of 

 Takanora, or Sandalwood Bay, and there continue to employ yourself, 

 making the various surveys directed in the copy of the instructions.) 



Leave letters where you may stop, and place signal No. 2 on a 

 conspicuous spot; No. 1 will represent the Vincennes, No. 3 the 

 Porpoise, and No. 4 the Flying-Fish. 



In the event of your penetrating the ice, with the prospect of a 

 clear sea before you, you will steer to the westward, bearing in mind 

 that the only prospect of again clearing it is on the route you first 

 followed, or that supposed to have been taken by Weddell, between 

 the longitude of 35° and 49° W. 



On clearing it, you will proceed to carry out the foregoing instruc- 

 tions, to make the appointed rendezvous with the least possible delay. 



(It is my intention, if I am not detained by ice, to reach the harbour
